本研究的目的是确定踝肱收缩压和踝肱比的测量值的变异性，以评估其适用于下肢动脉疾病的流行病学研究。其中36人由4名观察员在两天内使用多普勒探头和随机零点血压计进行重复测量。踝关节收缩压测量的变异性与肱动脉收缩压测量的变异性相当。踝臂比的一次测量的95%置信限估计为. ±. 16%，降至.+-.两名观察员在两天内进行四次测量的平均值为10%。方差分析表明，测量踝肱比的变异性归因于观察员，天，测量的同一天的时间，重复测量是远远低于“生物”的受试者之间和腿之间的变异性。这些结果表明，踝臂比的可重复性是这样的，一个单一的测量是适合于大多数动脉粥样硬化性外周动脉疾病的流行病学研究。
The aim of this study was to determine the variability of measurements of ankle and brachial systolic pressures and ankle brachial ratios in order to assess their suitability for use in epidemiological studies of arterial disease in the lower limbs. Thirty-six had repeat measurements taken by four observers on two separate days using a Doppler probe and random zero sphygmomanometer. The variability in the measurement of ankle systolic pressure was comparable to that for brachial systolic pressure. The 95% confidence limits of one measurement of the ankle brachial ratio was estimated to be .+-. 16%, reducing to .+-. 10% for the mean of four measurements taken by two observers on two days. Analysis of variance indicated that the variability in the measurement of ankle brachial ratios attributable to observers, days, timing of measurements of the same day, and repeat measurements was considerably less than the "biological" variability between subjects and between legs. These results suggest that repeatability of the ankle brachial ratio is such that a single measurement is suitable for most epidemiological studies of atherosclerotic peripheral arterial disease.
